What is self-discharge?
Self-discharge, also known as charge retention, refers to the ability of the battery to store electricity under certain environmental conditions in an open state. In general, the lower the battery storage temperature, the lower the self-discharge rate.
Why use a low self-discharge rechargeable battery?
The electrochemical structure of the battery itself determines the inevitable loss of battery capacity, which is due to self-discharge. In general, the self-discharge rate of alkaline batteries is relatively low. So the so-called "low self-discharge" is mostly for rechargeable batteries, especially nickel-metal hydride rechargeable batteries. This kind of battery has received great popularity because of its high discharge power and no memory effect.
